Analysis of the Interlaminar Crack Initiation in Mixed-mode I+II Composite Fracture Specimens
(Budapest University of Technology and Economics, 2003)
The interlaminar crack initiation in mixed-mode specimens was investigated through two- and three-dimensional finite element models. Elastic analysis was conducted to understand the crack initiation in glass-fibre/vinylester ...
Approximate Interlaminar Fracture Envelopes for Unidirectional E-glass/polyester Composite
(Budapest University of Technology and Economics, 2005)
In this paper an experimental study is performed in order to determine an approximate interlaminarfracture envelope of a unidirectional E-glass polyester composite. First, the pure mode-I fracturetoughness is determined ...
Comparison of some Data Reduction Schemes for Composite Delamination Specimens
(Budapest University of Technology and Economics, 2004)
Three different solutions for orthotropic, beam-like fracture specimens were compared in the currentwork. A beam theory-based approach was developed previously by the author. Another solutionbased on refined plate theory ...
A nonlinear observer for flexible joint robots
(Budapest University of Technology and Economics, 2002)
This paper presents the design of a kind of semiglobal nonlinear observers for flexible joint robots which needs the measurements of the positions of each motor rotor and link. For the proposed observer, the error equation ...
Fetal Pulse Oximeter for In Situ Monitoring during Labour and Birth
(Budapest University of Technology and Economics, 2008)
The oxygen saturation of arterial blood which is normally measured by pulse oximeters is highly important. This paper introduces a miniaturization development of a non-invasive, reflective pulse oximeter. The aim of the ...
Impact of Business Culture on Empowerment
(Budapest University of Technology and Economics, 2008)
If a Hungarian´s father for example is Dutch and his mother is French, it gives him an understanding of the fact that if something works in one culture, there is a little chance that it will work in another. The situation ...
Combining Description Logics and Object Oriented Models in an Information Framework
(Budapest University of Technology and Economics, 2009)
We present an information integration system called SINTAGMA which supports the semantic integration of heterogeneous information sources using a meta data driven approach. The main idea of SINTAGMA is to build a so called ...
Numerical modelling of the mechanical process of particle detachment by finite element method
(Budapest University of Technology and Economics, 2000)
This paper presents a numerical simulation technique for calculating the strain and the stress state at every point of the surfaces, containing real surface topology and layered structure. Depending on the nature of ...
Rain attenuation time series synthesis with simulated rain cell movement
(Budapest University of Technology and Economics, 2009)
This paper proposes a stochastic modeling method to simulate the rain attenuation process in order to generate time series for high frequency terrestrial radio links. It is also the subject of this research to express the ...
Test Component Assignment and Scheduling in a Load Testing Environment
(Budapest University of Technology and Economics, 2008)
In this paper we introduce two major problems from the field of load (or performance) testing and our solutions for them. When testing the performance of a device (System Under Test - SUT), the test environment executes ...
